What kind of request would typically be used to retrieve data from a server without altering it?

• A. GET request
• B. POST request
• C. DELETE request
• D. PUT request

Answer: (A)

A GET request is designed specifically for retrieving data from a server without making any changes to it. It is one of the fundamental operations in the client-server model and is part of the HTTP protocol. When a client sends a GET request, it is requesting information from a specified resource, and the server responds with the requested data. This behavior is integral to web services and APIs, where fetching data is a common operation. The nature of GET requests ensures that they are safe and idempotent, meaning that making the same GET request multiple times does not change the state of the server; it simply returns the same data. The other types of requests serve different purposes: a POST request is used to submit data to the server, which can alter the state or create new resources. A DELETE request is specifically intended to remove resources from the server, while a PUT request often updates an existing resource or creates it if it does not exist. Thus, only the GET request aligns with the goal of retrieving data without alteration.
